Microsoft Exchange business email helps increase user
productivity while protecting business data. Exchange Server consists of a mail
server, calendaring software, and contact manager. It is a server program that
runs on Windows Server and is part of the Microsoft Servers line of products.
As part of the Exchange Server product line, Microsoft Exchange Server 2010
adds a number of innovative features, technologies, and services to the product
line.

Beneficial features of Microsoft Exchange 2010
include: DAG (Database Availability Groups), Client Access Server (CAS),
Mailbox Server Role may be combined with the CAS, RPC Client Access, cost
savings in required hardware, Personal Archive, and
enhancement of compliance and legal search features. As well, clients benefit
from: Administration delegation, improvements in Outlook Web App, distribution
groups can be configured to allow users to join at will or only with a group
moderator's permission, as well as ‘Shadow Redundancy’ which protects e-mail
messages while they are in transit.

Exchange 2010 Migration
can seem like a difficult task, however with the right step-by-step approach,
the process can be much easier.The
following outlines the steps involved with Exchange 2010 Migration:

Step 1. Planning: The first step involves identifying
all of the critical technical and business details that will guide the overall
direction of migration. You can use such tools as the Exchange Pre-Deployment
Analyzer and Exchange Profile Analyzer, but you should talk to others in the
business about the processes they rely on email for. The gathered information
is used with Microsoft’s website guidance to create the design of your Exchange
2010 environment.

Step 2. Deployment: The second step entails installing
each of the Exchange 2010 server roles in your environment, and then
configuring them according to your design. There should not be a problem
completing the deployment stagewhen you
know about the specific risks and take the appropriate steps to avoid those
risks.

Step 3. Testing: This is a critical step because it
will make known any problems before they have a chance to negatively affect end
users or production systems. Testing should include the business and technical
requirements that were identified during the planning step. One essential test
that must be performed is Exchange 2010 backup and recovery. It is important to
ensure that fully functioning backups are in place for the Exchange 2010
servers before any production mailbox migrations occur.

Step 4. Migration: You can choose between two
migration approaches. The first migration approach is called Co-Existence which
involves the mailbox data being migrated over a period of days, weeks, or
sometimes months. This requires additional set up steps, such as configuring
the legacy namespace in order that remote access methods such as ActiveSync and
Outlook Web App (OWA) work for users with mailboxes on both versions of
Exchange during the migration. The second migration approach is a full
migration which can take place in one weekend.This can be done for smaller
environments. If the full migration can be performed in a single window of time
you may not need to set up co-existence.

Step 5. Decommission: Decommission consists of a
series of required steps to make sure that features such as the Email Address
Policies and Offline Address Book work correctly. To make sure no legacy issues
remain, the old Exchange servers must be removed from the environment. After decommissioning
has been completed, Exchange 2010 Migration has been successfully performed.

There are many good reasons to migrate to Exchange 2010.
In terms of disk read/write performance, the Exchange Server 2010 database
engine is up to 70% more efficient than Exchange Server 2007. This means it is
possible to deploy bigger databases with bigger mailbox quotas on cheaper and
larger disks. Exchange Server 2010 also has one high availability option for
Mailbox servers which is the Database Availability Group. Moderated Transport
permits distribution lists and mailboxes to be moderated by a non-admin user.
As well, the ‘Mail Tips’ feature, when used with Outlook 2010, will warn
clients of such email mistakes as doing a‘reply all’ to a large group, or
sending sensitive emails to external parties. Exchange 2010 Migration is much
easier and less complex when you understand the steps involved in the migration
process.
